Although it’s been just three months since she welcomed her first child withAlexis Ohanian, daughter Alexis Olympia, the tennis champion already has a hard time thinking about when the time comes to stop breastfeeding.

Many women responded withtheir own experiences, including Broadway starAudra McDonald. “I nursed my older daughter until she was almost 2. Still going with my 1 year old right now,”she tweeted. “You’ll know when it’s time to stop. Enjoy! She is beautiful!”

Still, Williams has been itching to get back on the court. In October,it was announced thatshe will make her competitive comeback to tennis in 2018 to defend her title at the Australian Open — the same tournament in which she beat sister Venus in the final while pregnant.

During an October news conference, tournament director Craig Tiley confirmed Williams “is planning” on playing in the January competition.

“Serena will be back,” Tiley said, according to Sports Illustrated. “We look forward to welcoming her and again go on that journey of breaking the all-time record for the most number of Grand Slams.”
